Nice tip, thanks. However I need to fit a mini servo mks95. Will that work?

Hmm, sure about that?

FBL blades just have slightly more lead weight added to the tips than the FB blades. This helps add a little stability when you don't have a flybar, making the FBL controllers job a little easier.

No problem at all to use FBL blades on flybarred heli, all it does is make it more stable. In fact, it is often recommended by the blade manufacturer if you want smoother precision flight, but will slow down cyclic response for 3D flight.

Also, FBL blades will give you more pop due to the additional rotational inertia.

Anyway, don't just trust me, see what a leading manufacturer has to say...

"Edge 523mm Premium CF Blades - Flybarless Version!

EDGE high performance CF rotor blades are new premium blades that have been specifically designed for today's model helicopters. EDGE rotor blades have been optimized for use with today's light weight, high powered models with increased cyclic pitch. While these blades are ideal for aggressive Flybarless 3D performance, they can also be used for more precision FAI & FC3 flying on traditional flybar machines.

Flybarless Edge blades may be flown on flybarred helicopters for a smoother and less aggressive FAI style cyclic response."

THe FB blades gives you more pop on FB and FBL helis

FBL blades are designed for helis with no flybar due to this it's been strictly manufactured for FBL only. You get more precise movements out of this especially hard manouvers.

There's a video of a pro testing out the difference between FB and FBL blades and on how they perform on FB helis and FBL helis.

If i ever find it for you. I'll post it up for you. It's really informative as he walks you though each manouver and shows the differences in flight performance.

Note: edge don't mention about smackdown. FB blades perfect for smack down and hard manouvers FB blades can be used in FB helis and FBL helis

FBL blades are only designed for FBL helis.

Both of those are made for a mini servo. If you need to fit a micro servo everyone makes CF adapter plates for $2

I bought two of those. The metal is much thicker than the thin silver ones that are flexy and break. They have gussets machined in too. The problem with the ones I bought was sloppy threading, frame screws wouldn't tighten at all and servo fit was very tight due to the mount being narrow. I drilled the frame and tapped one out to 3.0 mm, the other is still in the box. +1 mhills51 on the standard plastic servo mount and adapter plate if needed.

Happy Flying !!!

Do you have a link to the plastic mount and adaptor?

Very interesting on the biology of the fbl blades. I did hear that people liked the hobby cool cf blades did I not?

Yes, they are designed for FBL to help add mechanical stability that is normally added by the flybar, but it's fine to use them on a flybar heli if you want a more stable and precise, less aggressive flying style. The manufacturer EDGE actually says that about their own FBL blades. (See quote in my previous post.)

I've read a lost of post about guys giving their opinion on which blades they prefer, and how those blades performed. They often will talk about how agressive the blades are, and how much 'pop' the blades give. I then go and look up the specs of the blades they are talking about, and their comments almost always consistently align with the following two points: the lighter blades are more aggressive, the heavier blades give more 'pop', regardless of whether the blades are designated as FBL or FB by the manufacturer.

Interesting to see how much weight the different manufacturers add.

Align 325D (FB) 20g each
Align 325D 3G (FBL) 23g each

Edge FB 21g each
Edge FBL 24g each

pitchp, you trying to mess with my head?

The first video you posted said the FBL blades had more weight added. The second video you posted said the FBL blades are more stable, and the FB blades are more aggressive. Exactly what I said in my first post.

Hey, when are you coming up north next? We need to have a our own little fly-in together. Let me know, it'd be real cool to get together.

Well the plastic you can get anywhere they sell Align parts the adapter in the states is a little more http://tarot-rc-heli.com/Servos/450-...OR-PLATE-HENGE but you can get them over seas for around $2 http://www.oomodel.com/rudder-servo-...7-p-60939.html

Bud, I'm thinking of moving further up north (Cairns or Goldcoast). I'm over the melbourne weather (always windy and cold). Have you been to cairns??

It's been 37 years since I was last in Cairns, so I'm guessing it's a changed a little since then. My sister used to live in Townsville, not as far north as Cairns, but damn it was HOT!! I guess you get used to it though as I remember her husband putting on a jumper because it was a chilly 26 deg C, LOL. I have a brother on the tweed coast, the weather there is perfect if you can find yourself a job. Anywhere on the Sushine coast would be hard to beat.

what is the difference between the 2? and is the robird any good? I heard some reports of a tail bounce on the 450
I think the tail bounce on the Robird might have been caused by the brake setting being reversed when you reverse the gyro direction (basically you have to set it backwards if you reverse the tail servo). However I'm not going to move it back to the 450 just to find out.

Cheers,

The options are much more intuitive because they do things that make sense to normal human beings. Stop controls how fast the helicopter stops rolling, Agility is how much direct control input there is into the swashplate (as opposed to gyro input, decreasing it makes it more stable but less agile), Rate is how fast the roll rate is, etc.

Most of the setup videos on Youtube are now wrong because they changed the setup software quite a bit recently. But it's not hard to figure out (main change is that the subtrim was moved to the collective pitch menu and there is now subtrim for min and max collective as well as center)
